We've been hearing about Samsung's smartphone with a foldable screen for what seems like an eternity, but it looks like we'll have to wait a little longer to finally see the thing. Flexible screens have been demoed at trade shows for years, but getting them into a production-ready phone is another matter entirely. Samsung had seemed the most likely to make this dream a reality, but it must be as hard to do as it sounds — the project keeps getting put back.

Yesterday at Lenovo's Tech World event, the company demoed two concept products that were, frankly, kind of amazing. A foldable tablet-phone, and a bendable wrist-phone. While the on-stage demo didn't really tell us much about them, I sat in on a talk where we were allowed to take a closer look (though not touch, sadly) at these concept devices while learning more about them though.
